In the Case of freight ours which are ertea'y heated, it is neeessnry that the propef temperature shoud he l'uzintened in the our with e minimum amount of etten- 'Lon on the pari; of 'ih trein operator. the same ltime "n3 is. essential that ,here Should he no danger of the ce1' hiking fire from the heating 'tevce which ie employed.

The operation of my burner may now be readily understood. 'When the burner and the vaporizing tube lat are cold, as when the` burner is not in'opera-tion, the valve seat 15 is seated against the ball 16 so that liquid fuel, which is'in'troduced into the reservoir 11, cannot pass beyond the ball 1G. In order to start the burner, 'liquid fuel, such as alcohol, is placed 'iu the pan 37 and lighted, thereby heating the vaporizing tube 14 and causing the same to expand, and moving the valve seat 14 away from the ball 16. Fuel lfrom the reservoirll now flows into the vaporizing tube 14, and since the latter has become heated, the fuel isvaporized. The vapor passes through the port 27' into the valve casing 2l at a. rate which isl regulated by means of the valve stem 23. The vapor then passes outwardly through the pipe v28 and through the 4 aperture 30. This vapor next.'passes into the open end of pipe.,31 having entrained a considerable amountvof air in. its passage from the aperture 30 to the pipe 3l; this mixed vapor and air then passes through the pipe 31 to the burner 82' and thenthrouhthe holes33 and 35. The vn or ,is lightedbafterit passes through these ho es. It will now be apparent that the vaporizing'tube'll is kept heated by means ofthe flame which results from the vapor passing through the holes 35, and thus the valve seat 15 is kept separated frein the l 16, and at the saine 'time the liquid :fuel ing from the vaporizing tube is volatilized. If the flame from the burner is extinguished, by accidentuor otherwise, izing tube will contract, and the flow of fuel from the reservoir 11 will be cut ofi, thereby i preventing waste oi' fuel and danger of causing the car to catch fire.

Wha-t- I claim.L is:

1. A burner having an expansible vaporizing tube, a valve casing carried by the inlet end of the tube, a valve stem carried by and within the tube, a. 'valve carried by the stein and located within the casing, the stein be ing provided Withan outlet' port communieating with the interior of the vaporizing tube, and a vapor regulating ou tlet valve for said port, substantially as described.

2. Alun-ner including a burner body, an.

expansible vaporizing' tube extending through and prejecting'at opposite sides et the burner body, the inlet end of the tube, a valve stem cerf ried by and within the tube, a valve' carried by one end of the stem and located within the easing, the opposite end of the ste-u1 being provided with an outlet .regulating outlet valve forsaid port, and a rconduit communication from the port to th burner body, substantially' as described.

the vaporn port, a vapor a valve easing,I carried' by A burnen having an eupansible vapon tube, a valve easing carried' by the inlet end of the tube, a valve stem within and projecting at opposite ends-of the tube,y a. valve carried byone end of the stem and located in the casing, an external block provided upon the other end of the stem eateriorof4 the tube; said 'end of the stem having an',

outlet port therein, and an outlet valve easing for said port, said valve easing being connected tothe expansible tube and clamping the valve stein block between the vtube andthe basing, substantially ,as described.
